Your answer is incorrect.  When a chemical is absorbed it passes through cell linings of the absorbing organ (in this case, the gastrointestinal tract) into the interstitial fluid (fluid surrounding cells) within that organ. Gastric fluid is present within the stomach. The toxicant leaves the gastric fluid or intestine by passing through the membranes of the cells lining the GI tract. It is then in the interstitial fluid and can enter nearby body cells or enter the blood of the vascular system for systemic distribution.
